Experimental demonstration of quantum contextuality on an NMR qutrit
Shruti Dogra, Kavita Dorai, Arvind
We experimentally test quantum contextuality of a single qutrit using NMR. The contextuality inequalities based on nine observables developed by Kurzynski et. al. are first reformu…
Quantum state estimation using weak measurements
Debmalya Das, Arvind
We explore the possibility of using "weak measurements" without "weak value" for quantum state estimation. Since for weak measurements the disturbance caused during each measuremen…
Experimental construction of a W-superposition state and its equivalence to the GHZ state under local filtration
Debmalya Das, Shruti Dogra, Kavita Dorai +1
We experimentally construct a novel three-qubit entangled W-superposition () state on an NMR quantum information processor. We give a measurement-based filtratio…
Measurement-based local quantum filters and their ability to transform quantum entanglement
Debmalya Das, Ritabrata Sengupta, Arvind
We introduce local filters as a means to detect the entanglement of bound entangled states which do not yield to detection by witnesses based on positive (P) maps which are not com…
